Of course it's potentially dangerous but just know, NEVER try to move a Basset who reacts like this! BRIBE. This breed is a Pack breed and much as mine wouldn't react like this (they know better!) if you get one, more often a male, who does, you don't push it. He will regard things, and places as 'his' as he would have had to in a pack situation. And YOU have become is pack, so be aware.
Instead of picking up (if you still can!), pulling or pushing, you AVOID/PREVENT the situations that might result in this first, and you TRADE/BRIBE - in this situation, make what's on the ground off the bed WAY BETTER. No more picking up - have a slip lead which you can drop over his head if 'force' is necessary.
With Bassets, you totally avoid 'confrontations'. Again with the applied psychology - make what you want, his 'idea'.
Just to add I had this situation, just once, with our first Basset who, due to my ignorance, managed to get on top of a crate I had our bitch, in season, in. The crate wasn't the strongest, and apart from needing him off there, I feared it was going to collapse with her in it. I reached to pull him off and he bit me. Phoned hubby who came back from work immediately (he was able to in the job he had at the time) and took him off to kennels where he spent the rest of the time she was in season.
